HYDROCARBON-LIGHTING SYSTEM.

SPECIFICATION forming part of Letters Patent No. 702,406, dated June 17, 1902.

Application filed May 29. 1901.

To aZZ whom it may concern.-

Be it known that we, FREDERICK A. CODY and ROBERT D. CODY, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and usefullmprovementin Hydrocarbon- Lighting Systems; and we do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to hydrocarbonlighting systems of that class which are designed to light houses by the aid of local burners, a reservoir for the hydrocarbon, and conducting-pipes between them. The kind of hydrocarbon for which this invention is at present intended is gasolene, and insurance companies have placed a limit of one gallon as the'greatest amount of this fluid that will be permitted to be in a house at one time while the houseis insured.

The object of our invention is, therefore, to supply each house with gasolene to the amount permitted and means for connecting the house-supply with a reservoir for unlimited supply located at a safe distance from the house in such a manner that an unskilled person may operate the device with certainty and safety.

To this end our invention consists in the hydrocarbon-lighting system hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure I represents an open room of a house, a reservoir which should properly be located some distance from the house, and our hydrocarbon-lighting system, shown in a somewhat diagrammatic style, connecting the reservoir with burners in thehouse. Fig. II represents in longitudinal vertical section our double two-way cock.

Numeral 5 represents a room in a house provided with burners 6 and 7, adapted for burning gasoleue and connected by a distributing-pipe 8 with the outlet-port 9 of our double two-way cook 10. 11 represents a reservoir, that may be located at a distance from the house to be safe, for containing a large supply of gasolene.

12 represents the filling-plug; 13, the valve for attaching an air-pump; 14, the outlet for gasolene, and 15 the outlet for air.

16 and 17 represent two tanks of the ca- Serial No. 62,383. (No model.)

pacity permitted, say one gallon each, to be located in the house, and they are arranged to be filled from the reservoir 11 one at a time, as follows: A pipe 18 connects the outlet 14 of the tank with port 19 of the cockcasing 10, a pipe 20 connects 'the port 21 of the casing 10 with tank 16, a pipe 22 similarly connects the port 23 with the other tank 17, and a passage 24 in the multiway valveplug 25 of the cook 10 may be turned to communicate between the port 19 and either of the ports 21 or 23. 26 is a pipe communicating between the'tank l7 and the port 27 of the cock-casing 10. 28 is a pipe communieating between the tank 16 and the port 29 of the casing 10, and the valve-plug 25 may be turned to bring the two-way passage 30 in communication with the port 9 and either of the ports 27 or 29. 31 isa pipe communicating by means of branches 32 and 33 between the upper portions of the reservoir 11 and the two tanks 16 and 17. These pipes are always open for free transmission of air-pressure from the reservoir to the tanks. The pipes 26 and 28, being discharge-pipes for the tanks 16 17, extend nearly to the bottom thereof,so that they may conduct away nearly the other tank 17 through its discharge-pipe 26, the port 27, passage 30, port 9, and circulating-pipe 8 to the burners 7 in the house.

The tanks 16 17 must be located enough be-f low the level of the reservoir 11 to permit the gasolene to run by gravity from the reservoir to the tanks, because the pipe communications described render the pressure of air equal at the inlet and outlet of either tank, so that air-pressure would not deliver the gasolene to the tanks if they were on a higher level than the reservoir, and if the pipe connections 31, 32, and 33 between. the top or air space of the reservoir and the tan ks were omitted so as to produce air-pressure in the tanks in one direction only--that is, through pipe 18-then the tanks 16 17 would be mere enlargements in the pipes and would never be emptied as long as a supply of gasolene lasted, so that they would not be measures for the gasolene.

The operation is as follows: The reservoir 11 is to be partly filled with gasolene at plug 12. Then the required amount of air-pressure is to be produced by pumping in air at the valve 13. Now the plug is to be turned to fill one of the tankssay 16with gasolene. hen that is full, the flow will stop of itself, as there is now no outlet for it. Then if the plug be turned the opposite way the inletpassage 24 will connect the ports 19 and 23 and gasoleue will begin flowing into tank 17 and at the same time the passage Will open communication between ports 29 and 9, and the gasolene in tank 16 will be forced by the air-pressure into the distributing-pipe 8 for consumption. Now whether a gallon of gasolene is consumed in a day or a year makes no diiference with this system. Nothing further has to be done but to use the burners when they are, required until the gasolene gets low in tank 16. Then plug 25 should be turned back to allow it to refill through passage 24, and this will also turn passage 30 to connect tank 17 with the distributing-pipe 8. It may thus be seen that the greatest amount that can be admitted into the house at once by this system is the contents of the two tanks 16 17 and no skill is required to operate it.

The plug-lever 36 has stops 34 35, fixed tolimit its movement, so that the operator has only to move it as far as it will go when more gasolene is needed and to keep a suificient pressure of air in the reservoir by occasionally pumping in some.

Having thus fully described our invention, what we believe to be new, and desire to secure by Letters Patent, is the following:

1. The combination of a reservoir, a plurality of tanks arranged below said reservoir, a valve-casing, a distributing-pipe connected to such casing, and pipes connecting said reservoir and tanks to such casing, a multiway valve-plugin the casing arranged to be turned to connect either of said tanks to the distributing-pipe and the other tank to the reservoir, and a connection between the upper end of each tank and the reservoir.

2. In fluid-delivery apparatus, the combination with a supply-tank, of plural deliverytanks, suitable pipes for passage of gasolene or like liquid connecting said delivery-tanks to said supply-tank and with a dischargemain, equalizingpipes extending between said supply-tank and said delivery-tanks, and suitable valve mechanism whereby when the supply of gasolene or like liquid is admitted from the supply-tank to one of said deliverytanks connection between said supply-tank and the other of said delivery-tanks is cut off and said delivery-tank thus cut oit from the supply-tank is placed in communication with the delivery-main.

In testimony whereof we affix our signatures in presence of two Witnesses.
